Abstract: Disclosed is an electromagnetic-force-balancing-type electronic balance having a magnetic circuit which includes a yoke 4, a first permanent magnet 1, a pole piece 3, a second permanent magnet 2 and a cover 5. A connection member 7 made of a magnetic material is disposed in an air-gap region included in the magnetic circuit. The connection member 7 may be disposed between the second permanent magnet 2 and the cover 5 or between the cover 5 and the yoke 4 to facilitate assembling operations. Alternatively, first and second gap-defining members 8, 9 made of a non-magnetic material may be disposed, respectively, between the first permanent magnet 1 and the yoke 4 and between the second permanent magnet 2 and the cover 5, to provide symmetric properties in magnetic sub-circuits so as to counteract an imbalance in hysteresis characteristic. The present invention can suppress adverse influences of a magnetic resistance caused by an air gap existing in the magnetic circuit of the electronic balance.
Abstract: An electrical assembly has first and second initially separated connection portions, of which the first is adapted to be secured to a first component, such as a microswitch, and the second is adapted to be secured to a second component, such as electrical wiring through insulation displacement, with the first and second connection portions further being capable of releasably fitting together, such as by means of a latch to bring the first and second components into electrical contact.
